can i get some scientific studies to show why l-glutamine is supposedly a good treatment for the cold? i saw some info on the nootropics board but no studies and im having trouble finding any on the internet.
 
i found this

Enhanced immune system

Cells of the immune system including the macrophages and lymphocytes depend on glutamine as a primary fuel source. In addition, it has been hypothesized that a high rate of glutamine consumption by these rapidly proliferating cells is required for sufficient nucleotide synthesis (14). Research indicates that low levels of glutamine within the body may result in the increased susceptibility to infections and illness due to a suppressed immune system (2). The ability to proliferate and the activity of immune cells in vitro have reportedly been suppressed in mediums lacking glutamine (15).

Furthermore, an increased rate of infection and illness (particularly infections of the upper respiratory tract) has been reported among athletes participating in intense, long duration sports activities (e.g. marathon racing) (16). It has been suggested that a decline in plasma glutamine concentrations may be one of the factors responsible for this increased rate of illness. Specifically, the activity of natural killer cells, a reduced number and proliferative ability of lymphocytes, and a reduced ratio of T-helper to T-suppressor cells may be the result of prolonged, exhaustive exercise (16).
